WESLEY R. GOODWIN, OF DECATUR, ILLNOIS.

STERlLIZlNG-CABlNET.

eacrrrcn'rron forming pm of Letters Patent No. 649,512, dated may 15,1900. Application lezl October 6, 1899. Serial No. 732,760. (No model.)

. a citizen of the United States, residing at Decatur, in the county ofMacon and State of Illinois, have invented certain new and usefulImprovements 'in Sterilizing0abinets; and I do hereby declare thefollowing to be a full, clear, and exact description of the invent-ion,such as will enable others skilled in the art to which it appertains tomake and I desire it understood, however, that the use of the inventionis not limited, but the same can be employed for various purposes.Heretofore it has been found entirely impractical to utilize awetsterilizing agent or material for sterilizing steel implements or toiletarticles, such as brushes, &c., owing to the fact that the moisturecarried by the steam, as an example, necessarily damages the articles.It has also been found impractical to use heat, inasmuch as the degreeof heat often injures the articles. My invention is designed to overcomethe objections to the above type of sterilizcrs and is designed'moreparticularly for use with chemicals or disinfectiug agents the vapors ofwhich are generated bythe application of a'flame or relatively-smallamount of'heat and penetrate the entire cabinet, ster-V ilizing thearticles therein. L

To this end the invention comprises a cabinet conveniently formed of aseries of drawers formed so that the sterilizing agent will penetratethe same, sterilizing the articles con` tained therein without heatingor dampening the same.

Theinvention further consists in the particularconstruction andarrangement hereinafter described.

In the drawings l have shown the steril-` net.

struction can be made without departing from the nature and principle ofthe invention.

In the drawings, Figure 1 is a front elevation, and Fig. 2 isalongitudinal vertical section. y

ln the drawings. A represents the outer casing of the cabiuet,comprising a closed back and sides.

B designates the front door, which is couveniently hinged at one side. f

The cabinet is formed with a series of transverse supports C and aseries of upright su pports C', the same being dispersed at properpoints to form guides and supports for the various receptacles orsliding drawers. These drawers conveniently consist of four drawerssubstantiallyrectangular incross-scction arranged in pairs on oppositesides at the bottom, as at D, leaving an unoccupied space E between thelower two of the series and at the center-of the cabinet. The sides ofthe lower two of the drawers D are perforated, as shown atd. Above thespace E is an `oblong drawer D2, having a perforated bottom; Above thedrawers D and D2 are two oblong drawers D3, having perforated bottoms,and above these are conveniently arranged four relatively-smallerdrawers D4, each of which is provided with a perforated bottom. Each ofthe drawers is supported on a rest, and they are separated by theuprights, so that they' `which is an escape-pipef, having a damper f'therein.

The cabinet is conveniently supported on suitable legs a. and has abottom A', formed with a central opening a' therein, located at thecenter of the space E. Over thisopening is placed a metallic diaphragmH, the same being supported on.` legs h to form a clearance between thesame and base of the cabi- In line with the opening his placed theburner of the lamp or gas-xture, and below the diaphragm areplacedsuitable receptacles containing a vaporable sterilizing chemical.The lampl is of any convenient style or formation and preferably of thealcohol-burning type.

In practice the smaller drawers are designed to contain the implements,while the larger IOO ones lare designed to contain towels or other'cloths, fabrics, dto. rIhis, however, is Wholly arbitrary. The cabinetis designed to be un.-

A the lower draw ers and perforated bottoms of the upper drawers,thoroughly satnrating the interior of the various drawers andsterilizing the articles therein contained. By governing the damper inthe exhaust-pipe the movement cf the sterilizing-vapor is governed,andthe pipe may be conducted to any convenient point of discharge. Inpractice I purpose to employ duplicates ofLthe drawers, so that onecanbe removed and the contents, as a soap-dish, with necessary brush,and another replaced while the contents of the one removed are beingused.` This, however, is entirely arbitrary. IIaving thus described myinvention, what I claim as new, and desire to secure by Letters Patent,is

l. In a sterilizing-cabinet comprising a series of separated drawershaving perforated bottoms and an aperture in the base of the cabinet, aburner in line with-the aperture, a diaphragm above the aperture and inline therewith, means adapted to contain a suitable sterilizing mediumsituated in the line of draft from the burner, andan escape ati the topof the cabinet and a governor for the same, substantially as described.

2. In. a steriiizing-cabinet, the combination with the walls of thecabinet, a series of `d rawers therein having perforated bottoms andarranged to leave a heating-space therebelow, of drawers in the base ofthe cabinet having perforated sides exposed to the heating-space andmeans for supplying heat comprising a burner leading to an opening inthe cabinet, la diaphragm in the cabinetabove said opening, and meanslocated near said diaphragm and in the line of draft from the burner,adapted to contain a suitable sterilizing medium, substantially asdescribed.

3. In a sterilizing-cabinet, the combination with the walls, of a seriesof perforated drawers within the cabinet, arburner communieating withthe cabinet through an aperturev in the bottom thereof, and meansadapted to support a suitable sterilizing medium'in the line of draftthrough the cabinet, a domeand damper-exit from the dome, substantiallyas described. I

4. In a sterilizng-cabinet having a suitable outlet, the-combinationwith the walls of the cabinet, drawers supported therein and arranged toleave a centrally-disposed heatingspace in the lower portion of thecabinet and perforated respectively at the sides and bottoms to permit athorough circulation, means adapted to contain a sterilizing medium atthe lower portion of the cabinet, substantially as described. v f

Intestimony whereof I aix my signature in presence of two witnesses.
